A free public safety tool
Find out if your wallet is still yours.
Attackers can quietly attach a drainer to a crypto wallet, or empty it after getting hold of a device. This tool checks public blockchain records, shows you what to do, and helps you report it. It never asks you to connect a wallet, sign anything, or type a seed phrase.
Start here
What's going on?
The right first steps depend on how the wallet was compromised. Pick the one that fits.
I want to check if a wallet is compromised
Funds vanished, or you just want to make sure a wallet is clean.
- Checks for malicious EIP-7702 delegations
- Shows the full delegation history
- Tells you exactly what to do if it's hit
Someone had access to my device, and my crypto is gone
A repair shop, a support session, a shared or stolen computer.
- Builds reports for the exchange and the police
- Walks you through the urgent first hours
- Helps trace the funds to their cash-out point
Not sure which fits? Start with the wallet check — it will tell you whether a drainer is attached, and point you onward from there.
How it stays trustworthy
A tool for people who've just been robbed has to earn trust by asking for nothing. Here's how it works.
01 You type an address
Just the public wallet address — the same string you'd paste into a block explorer. Nothing that could move funds.
02 It reads public records
The tool looks up delegation records that are already public on the blockchain and compares them against a list of known drainer contracts.
03 You get a plain answer
Compromised, exposed, or nothing found — with the history laid out and clear next steps. No jargon you have to decode.
04 Nothing is stored about you
Addresses you check aren't published. A community warning list exists, but only if you opt in, and it's removable on request.
What this tool can do
- Detect a known malicious delegation attached to a wallet
- Show you who took control and when, in a plain timeline
- Give you the right first steps for your situation
- Generate reports for exchanges and law enforcement
- Help you warn others if you choose to
What it honestly cannot do
- Tell you a wallet is safe — it only rules out one specific attack
- Detect a stolen key that hasn't been used yet
- Explain how your keys leaked — the chain doesn't record that
- Reliably identify the attacker — that's work for investigators
- Recover anything — no one can reverse a settled transaction
One warning worth more than the rest: anyone who contacts you offering to recover your stolen crypto for a fee is running a second scam, aimed at people who fell for the first. No private service can reverse a blockchain transaction. Real recovery only ever happens through law enforcement and the courts — and it starts with a report, not a payment.
Keeping it running
This is free, and always will be.
WalletCheck doesn't charge to check a wallet, and it never will — a safety tool that asks robbed people for a payment isn't a safety tool. Running it costs very little: a domain and some hosting. If it genuinely helped you and you'd like to chip in toward that, you're welcome to. If you can't, use it freely and share it with someone who needs it — that helps just as much.
Support the hostingOptional. Never required to use the tool. We'll never ask for a card or a payment to show you your result — if any page ever does, it's not us. Funding is kept public so you can see it only covers costs.
